Today started a Thanksgiving/Winter Sale on itch.io. There are 3 levels of discounts, based on the game "age". Older games are 50% off, last year games are 40% off and Amber is 20% off since was out only 8-9 months ago:

Even setting up the discounts was much easier than with BMT micro, took me just a few minutes the only major issue right now is that DLCs aren't supported well, so for SOTW DLC the only way is to get it on my own site with BMT. Sorry about that, I already asked them if it's possible to implement them properly in future.
